Kangaroo fun with out the fun ! please help

Hello i seem to be a regular when it comes to plroblems with my clipper

right heres how it is my 1.8 8v ex engine clipper was running for up until a few days ago i was just driving along at about 50 to scared to go faster lol when out of no where it started to hesitate and then it started to kangaroo very violently i took my food off the accelarator and as the car slowed down so did the revs and then the car cut out so i bumped it back into life and planted my food down it was very very slugish but no kangarooing but as i let fo the pedal back comes the bouncing, i checked all the leads out when i got home found my king lead was broken so i repaired it started the car up started first time and idled as lovely as a 23 year old clipper can i took it for a run down the road it drove fun but then 10 mins later back to bouncing and its been like this since practicly unusable

forgot to add it put a new dizzie and arm on it this morning no change

someone please help

Hi mate, I had similar sounding problem last week. Is your pump making a bit of a buzz or scream? If so it could be that the filter on the end of your in tank lift pump is blocked like mine was.   Cleaned it up, all is ok now

ive got a lift pump on the engine i dont think i have one in my tank unless i do but then i have 2 pumps lol

What carb you got original 2e2 or weber 32/34dtml?
On carbs you only have the one fuel pump which is located at front bottom area of block just above the oil filter.
Clean your tank out as there will be small piece of rust from filler neck in past for sure, have you replaced the filler neck? or has it been replaced in past?
remove fuel sender form underneath the rear bench, there is a small filer on the end wit approx 16 tiny holes, you can simply pull it off and clean it out, whatever you do DO NOT leave it off, refit it.
Then if not been done replace the fuel air vapor separator which is located middle front of block near rocker cover.
Clean the carb i.e remove it and keep it upside down as you do so, therefore no dirt will end up back in the carb.
You got any pics of your carb and block area please for me to look at?
Clean air filter or replace if you have standard paper type

Thanks for the reply this morning I took my fuel sender out and went fishing got a load of rust out of the tank I cleaned the end of the sender out and replaced it all and it seems to
be resolved it's still got no pick up if I
plant my foot down but I think that's more of a timing issue I'm gonna replace my filler neck at some point soon in work thanks again forthe reply I'll
also change the little resovoir that feed the carb and the return

Spoke to soon drive it round all day not a single jolt then went to pull out the junction up the street and flat right in the middle of a main road proper bummed out

How did you clean out the fuel tank of rust/dirt?

ran it down do it was near on empty under the back seats is an inspection plate take that off and theres the fuel sender take the plug off and the 2 pipes remeber whish one goes where twist the top i used a screw driver and wala inside the tank take a magnet and a piece of string and go fishing its fun to see what you get out

I'd say there's still dirt in the fuel tank then. I've cleaned out loads, basically you can't get good enough access through the little hatch so you need to take it out to be sure. The magnet can pick up metal, and rust which still has some non-corroded metal, but it can't pick up dirt (non-magnetic) which can also find its way in there.

Another option is the vacuum cleaner but it needs to be an explosion-proof one.

ok then cheers I'll give it a go mate I'll just drop the tank don't fancy finding out if my vacum cleaner is non explosive or not lol
