Full throttle when started
 

I just pulled my SH .18 out of storage yesterday after sitting for 8 months. I checked the carb gap which was at 1mm. As soon as I started it, it went to full throttle( luckily I had the HSN set very rich so I wouldnt throw the rod.) Ive tried leaning the LSN out which lowered the reving a little bit, but im still spitting out alot of fuel. Also, as soon as I start it and take the glow plug igniter off it instantly dies. Now im at the point where even if the igniter is on it sounds the same trying to fire as if there isnt a glow plug igniter on it at all and the igniter has charged over night.

You prolly have a bad airleak,seal the backplate and under the carb with silicone,turn in the highspeed needle and count the turns if your like at 3turns try 2.5 Than lean the highspeed. your drowning the motor with fuel. If you drown it again take the plug out & turn your kit upside down and crank the motor to expel the axcess fuel..I'd take the glow plug and put it on the igniter to see if its glowing.If its still good it should glow brite orange,make sure to burn off the extra gas and before you put the plug back in. if your spiting fuel its way to rich try setting the lowspeed flush with the slide arm on the carb

What type of silicone would you use?

RE: Full throttle when started
 

anything from the autoparts store i use the black and red and the copper stuff

I bought the permatex ultra copper kind. if this doesnt help what else could it be?

set everything to stock settings and try again. could be bad seals in the carb. also tighten the head bolts (but dont go crazy on them)

also, did you bench test or was this in a car at the time?

It is attached to my buggy, but not tothrottle linkages or the transmission.

Sure hope you're using a throttle return spring or band.
