I am having a problem with my GRP motor. Let me give you the breakdown;

- I just cleaned the carb and inside the crank case
- I replaced the carb boot cause I noticed it was ripped
- I took out the low speed needle to install boot
- I replaced all the seals on ALL needles (HSN, LSN) and reinstalled them

I reset the needles to factory settings. This should make it really rich (my motor has about 3 gallons on it). I turned the HSN and the LSN in about .75 turns to lean it out.

The problem I am having is I think the motor isn't getting gas. When I start it on my bump box it will run until I pull the throttle. It will just die out, no decrease in rpms. I noticed that when I prime the engine(blow into the fuel line or place my finger over pipe), there is a lot of pressure and the gas will not flow to the carb. It acts like something is clogged or blocking it. BUT when I open the carb, gas will flow freely. Is this something they just do? Recommendations in settings? I pretty sure my clutch isn't dragging.

Should I just get a new engine since NOTHING is availalbe for these any more? The boot I bought is close to the same as the GRP. I creates a seal because when I open and close it you can hear suction. Is that right?
