Re: Poppet Valve Service

[PM T2]

Poppet valve has to move freely. You have to lift it by pushing on the stem from underneath. The poppet valve is spring loaded and needs to have pressure on it when you lift it off the seat. There is no primer button on that mixer.

Best way I’ve found to start those things –
1. open the fuel inlet valve that should be on the tank, then
2. open your needle valve about 1/2 to 5/8 of a turn, then
3. lift the poppet valve off the seat and let a few drops of fuel leak out.
4. Bounce the flywheel back and forth several times between compression to prime the crankcase, 5 or 6 times might be enough, if not you can do it more on the second attempt
5. Move the timer lever so that it is slightly to the port side (your RH side, if you are standing in front of the motor) of the centreline of the cylinder – in other words, around the 5 o’clock position, then proceed to
6. Pull the flywheel over through compression and see if it will bark for you.

Once the engine starts, it is normal to have to adjust the needle valve slightly toward the lean side to get her to smooth out.

Hope this helps.
