WIMPUS Posted August 24, 2014 Share Posted August 24, 2014 Hi all, A few months back i've fixed my waxstat jets to normal jets (the penny way or 2 eurocent way).But at the time i've heard that i best changed the butterfly's to solid one.Now there are butterfly's in it with a valve in them (waxstat). is this right ? :) Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted August 24, 2014 Share Posted August 24, 2014 The valve in the butterfly is a small spring loaded thingy.It's supposed to be some sort of anti-stall thing from what I hear. If you have chance, get rid! Quote Link to comment Share on other sites More sharing options...
ferny Posted August 24, 2014 Share Posted August 24, 2014 You can always solder it shut. Think someone on here did that once and posted photos. Quote Link to comment Share on other sites More sharing options...
Richard B Posted August 24, 2014 Share Posted August 24, 2014 I think one of the problems is the valve can upset the air flow when the butterfly is open. Also the valve can go weak causing lean running on idle.As you say, either cut it off and solder up the hole or buy new, plain butterflys.

WIMPUS Posted September 4, 2014 Author Share Posted September 4, 2014 Well put them solid butterfly's in today. Has a chance to clean the whole carb then also. Needed to set up the idle so it was running only just and then gone for a little test drive .. Stopped somewhere and adjusted the idle a bit and turned down the mixture screw about 1,5 turn..I know i when i last tested it with the colortune i needed to put the mixture 1,5 turn richer and then it was running good, otherwise popping and banging ! :BSo turned the mixture down and drove further on .. still driving great and seems to go better also :PAnd for sure my mpg will be getting better to ;)Now just need to get the colortune out again and set it up good ;) Quote Link to comment Share on other sites More sharing options...
Richard B Posted September 4, 2014 Share Posted September 4, 2014 If the spring in the butterfly gets weak, then a high depression will overload it.Then you have to richen the mix on idle, which puts everything out further up the range. Glad its better. You should see an improvement in mpg. Quote Link to comment Share on other sites More sharing options...

Glad its better. You should see an improvement in mpg. I guess it's going to be that then, i think they are also the original ones ... So 36 years old .. Will see now in the next few days ;) Quote Link to comment Share on other sites More sharing options...
WIMPUS Posted September 4, 2014 Author Share Posted September 4, 2014 This evening went to some family of mine and parked the car for an hour or 2 .. Normally then she started to pop and bang when i drive off .. Now nearly didn't need choke , started up straight away & nice and drives very nicely from in the beginning :PNow see for a very cold start (after a night standing outside), but i'm now it will be just good :) Quote Link to comment Share on other sites More sharing options...
