sirio issue

[beave]

i have a 27,11port sirio monster engine in my revo it starts and runs fine,after several minutes it won't accelerate. it idles but won't take fuel,feels like it is bogging down. i checked the clutch and exhaust gaskets and it isn't running hot.any ideas will be happily tried, thanks

Check the o-ring on the filler cap of the fuel tank. It can go bad and cause a mid tank lean condition.

also check the line between the tank and the muffler ...i had that happen to me with my wasp .26 ...it would idle fine ..but would not take throttle ..turns out the line had a tare in it right at the muffler

it sounds like it my be too lean. This makes the engine run hot. Richen the high speed needle 1/4 to 1/2 turn (counter clockwise) and after getting the engine running re-tun it.

The other thing that can cause the engine to run hot is if the brake linkage is not properly set. I have done this to my car in the past. What can happen is that at full throttle you are also putting on the brakes. Check to make sure that this is not happening.
