YM 1700 hard starting

So what "I'M HEARING" is>> u took a shower & put on dirty socks.. lol
{pulled the engine apart & put the old fuel system back on without getting it checked}

I apparently missed it, but exactly what PSI compression reading did you get?:confused3: Good compression, 400PSI+, good fuel at the right time and good air im/out is all you need.

 

[careyo63]

He hasn't. I told him to pull the injectors.#65 And if they're good check the compression and I believe between the two he was going to find the problem.

Am going to pull the injectors and clean them. If that doesn’t do the trick, the pump is next. Thank all of you guys for your advise!

Whatever you do, don't check that compression. . .. :confused3:

 

[B man]

Planned on it. Thx!

What ever u do>> DO NOT run the end of the tip across a wire wheel.!!!
That's a guaranteed trip to the "injector store."
I've never seen a compression tester adaptor for a 1700..??
UNLESS u have an old injector u can make it from?? I'm just thinkin out loud..

Thanks Winston..
..do u know what the other end looks like?? is it threaded like the actual injector, female threads UP IN the body & will only seal w/ their line??
or is it "standard" threads that u can adapt to a tester?

I has 1/8 npt threads for tester connection. I don't know but just assume the bottom end seals on a gasket when clamped down. Only assumption, have never laid my eyes on one.
