Thank you I will check these out90 is OK. Especially if you didn't hold the throttle wide open.
I'd look at the Needle Valve. Sometimes people us Stabil etc over a time and the Rubber tipped Needle valve will stick inside the seat.
Try this, disconnect the line from the pump to the top of the Carb.
Blow in that line. The force from your lungs should force that needle open.
If not, you'll have to take the Carb off, then the top off, to see if that's the problem
When you spray gas into the Carb, does it show any improvment at all? An extra burble or one cylinder try to start?
One more thing to check is the timing of the flywheel. Maybe you've sheared a Woodruff Key and the Flywheel is out of phase with the Crank.
Could it be the triggerYou have spark and fuel, do you have spark at the right time?
How did you check that Key?
You have to pull the flywheel off to check that key.
I have 90 psi in both cylinders a have fuel i have spark but it will not start using a automtive spark tester the spark with jump a gap of almost 3/8 of a inch any ideas
