Well, I pulled the tank, replaced all the lines.....now I get 15 minutes! The tubing was new, but must it must have had a pin hole or something in the supply line, I tried to do a "pressure test" (pinch an end and blow into it) , nothing seemed bad, but since I had it apart, I spent the $2 on fuel line. Anyone have an opinion on the best remote glow system?? I have/had a sullivan system on it and it cost me an hour of time yesterday figuring out it was not seating properly/grounding on the plug, left the cowl off and put the starter right on.... I noticed the last set of pics someone had the entire bottom cut out of the cowl, alot of you guys do this????

Saito 72 question, I have about 1.5 gallons thru it, 13x6 Master prop, 15% Wildcat syn fuel..... new to 4 strokers, the exhaust valve seems to squeek/click when it opens, I checked the clearance w/ the supplied tools, any comments/concerns/normal???? Is a 14x4 prop too much for the 72? I dont think a 13x4 is made??

Can someone explain the prop diameter = pitch = thrust = speed relationship?

Best prop for a UCD 46 w/ Saito 72?
Best prop for a GP Giles 202 w/ a Saito 100?
