Ours live in a cold shed on a 3/4" crushed stone floor.  

 

Bad. Very bad. 

 

We're going to need to renovate. 

 

Perhaps some nice smooth sand....

But they do have each other to give them solace and they are bred to handle the cold.

  Well, I finally installed a bulb type primer on my C101 the other day.  It's an 1/4" Attwood Universal High-Output unit. The only place to locate it so I can squeeze it, was between the steering tower and the engine, which meant I had to relocate the new gas filter under the shifter cover plate. Not the most ideal spot for a gas filter!  I wish they made a tank shut-off valve with a replaceable filter combination unit.              If I  had to do it over again, I think I would have went with a plunger pump style primer mounted in the vertical plate next to the amp. meter. 

  Now to figure out how to speed up the mower deck RPM by installing a smaller pulley on the middle spindle. Unfortunately, I have an older deck with the double D spindle shafts.

Did it solve the hard start issue?

Can you please post a link to this plunger type primer you were going to use? All I found was aircraft stuff and it's $$$$$

Would 90 deg fittings on the bulb solve the location issue and leave room for the filter?

I stopped by a local tractor shop and asked about an in-line primer.  He didn't have any but said they typically see marine use, and suggested I stop by a nearby boat shop.

I ordered online.

CORRECTION

FOUR for less than $18. 

 

 

Hopefully they'll last a bit. 

 

Attach the word Marine or Water to a part and the price grows.....

I just  installed one today on my 175.

 

Same area as the others.

 

I could feel when the bowl was full, there's a bit more resistance.  About three squeezes, maybe four tops.

 

I placed the filter after the bulb on top of the twin.  I don't see where it makes any difference where the filter is located, before or after the bulb.

 

I didn't use a clear filter last time, but that's a good idea, being able to see the filter fill up.

 

Here's a couple pics.  I made a support out of some galvanized and heat shrink tubing to keep the fuel line out of the steering gear.  That would not be good.  Note also the ty-rap looped loosely around the positive batt cable for more stability of the bulb to keep it from flopping around.

 

The vertical tube is the drain for the battery tray.

 

 

 

 

Yeah, I know I need a little paint touch up but she's a worker...

One of the reasons I've switched over to blue see through fuel line.

  Yes, the bulb style worked well.  This is  a picture of the plunger style I wish I installed.  Amazon has several for sale between $15. to $25.   It would have made for a neat factor looking installation.                                                      

[Jeff-C175 7,202]

I'm going to look into the plunger style when/if this one craps out.

 

Plumbing shouldn't be too bad.

 

Looking at those it appears they may not be adaptable to our machines.  Looks as if they are for 1/8 fuel line.  There's a tee fitting included in the package.  I can't grok how these are supposed to work.

IMHO, the reason for the filter being placed first inline is to keep dirt/crud out of the primer check valves.

I thought of that too.  I wonder how 'precision' those checks are.  Probably simple rubber flappers.  Maybe 'self cleaning'.

 

If concerned, another filter could be installed back at the tank I guess.

 

I might be more conerned with ethanol gasoline attacking the bulb causing bits of rubber getting into the carb.

 

By the way, someone earlier stated they thought there was a single check valve in the bulb.  I believe there has to be two, one at the inlet and one at the outlet.

One more legit reason to go E-free

I can't find it around here.  Maybe at the racetrack or marina but then the price is double!

We had a nice event recently. 

I was buying it in NH. (l live near the border).

It became available at 2 places a little out of the way from my work to home commute but less than making a special trip. AND it's over a dollar cheaper per gallon. 

Win, win!!

in my area ethanol free gas is also referred to as RV fuel.  Typically 87 octane with  a much better price than 'racing fuel'.  My KT-17 runs great on 87 octane.

This type of primer is made to squirt a small amount of fuel directly into the engine, it basically replaces a choke.  I guess it could be plumbed around the fuel pump using appropriate tee's and small fuel line.  My question would be how many pumps would be needed and what pressure is developed.  Pressure too high will push the float valve open and flood the engine.  I used these troublesome primers in snowmobiles back in the 1970's and 80's.

Kinda what I figured out after looking at the pics on Amazon. 

 

Not gonna prime the float bowl of the carb...

 

So looks like I'll stick with the squeezy bulbs then.

 

By the way, I 'blew' through the bulb (before I installed it!) and you can blow in one direction, but not the other so I suspect that adding the bulb will also prevent 'drain back' into the tank.  Might only need to squeeze this thing after the machine has set for some long time.
