We talk about the bleeding blisters first!
when you operate the pull-start system,there are some tips.
1)Before you start the engine,pull the line out fully. Then you know the total length of the line. Don't over pull it out!
With a strong arm you will damage the pull-start system.
2)Why you got some bleeding blisters is because your finger touch the heat sink(cooling head). So it is important that you don't need to pull the starter from the start.
You can pull the starter around 10cm out slowly,then just start to pull the starter between 10cm to 40cm distance continuous. Then your finger or hand should not touch the heat sink.
3)ok let us try to start the engine. Use your knee press on the tyres to fix your monster truck. Right hand pull the starter line out around 10cm. Left hand finger block the pipe then pull the starter line several times. Make sure the fuel be pumped into the carburetor. It not,that means the LSN is too lean or even cut the fuel supply at idle position already. Or the carb is close fully and no air bypass.
4)Put on the igniter and make sure the idle opened. Start to pull the starter between 10cm to 40cm distance continuous. After several time pulling,the engine should be started.
5)If it still not work,it most have some thing wrong. Stop to keep on trying. Try to find anything wrong. Check if the plug is fine and the igniter battery. Check if the fuel enter the carb already. Check if the idle is open enough. If you can see a lot of fuel flow out from the tuned pipe,that means the HSN is too rich.
6)After the engine started,don't loosen your hand suddenly and let the starter line return very fast.
That is not cool! It may snap the return spring. You should let the inner spring return the line slowly.
Above process is what I start mine D28M. Hope you understand my poor english.
For you information.
