Hi all, After having some clear jelly like substance block my carb I’ve just finished replacing all fuel lines cleaning tank and fitting a new carb and filters on my 84 110 with a 2.25. I went to start it today and all it does is crank doesn’t remotely sound like it wants to fire. I have fuel and spark (albeit possibly weak but had no issue prior to this) I have replaced the coil and triple checked the timing. Does anyone know of anything else that could prevent it from firing? Motor has 15,000km on it since rebuild.
 
Could be a number of things, more jelly in the fuel line? I would dribble a little fuel down the carb throat and turn it over. If it fires and runs briefly then you still have a feed problem. Does not fire is ignition problem.
 
I agree with tottot, there is still a fuel starvation issue. Do as he sugests and put an eggcup full of clean, fresh petrol straight into the top of the carb and turn it over with the choke out. Make sure the battery is fully charged. A series should fire even with a weak spark and less than perfect timing. Also check the air mixture screw is about one and a half to two turns unscrewed. Good luck.

I guess you have a Weber 32/34 DMTL carb? If so are the solenoids on the carb connected to a live feed? Check the connectors are clean and tight.
 
When I suspected my carb was gummed up I was able to get the engine to fire just by turning it over and spraying Easy Start directly through the carb air intake.
That will at least tell you if it's spark / timing issue.
Did you empty out the fuel tank and give it bit of a flush out? New fuel lines should be fine as long as they're not pulling air in - check for leaks.
New carb could be set up wrong or even plain faulty.
