No petrol coming through??

Hi.

Hey thanks very much for all your help. I have to confess that my last post stating that........ "I followed the above steps etc.. etc... The end result was .. no discernible difference".

Well.... I lied.. I didn't actually take it for a spin, so I was talking out of a hole in my arse.

I just got back from a spin up the road... (Heard sirens going past when I parked in the garage...:-\" She is running much better. Still struggled up my steep drive (even when warm) but cleared her head and gave a pretty decent performance. I'd say performance went from a 2 out of 10 to a 7/10.

Thank you very much. That goes for everyone else as well.

I think I might have another go at the "highest/smothest rev" adjustment over the weekend to see if I can get her a bit better and will accept the consensus of opinion regarding the petrol filter (will have to find a jointer) at least until I find a decent sized low pressure one.

Just for the record... She is running better now than when I got her.

Keep forrgetting to ask you (psyguy) what is your screen, whee did you get it and how much $? It looks just the right size and as good a style as any I've seen out there.

Progress update

I have the idle mix screws set about as good as I can get them.

With the exception of the following issue she appears to be running sweet.

The issue

When accelerating (opening throttle) She starves..fires...starves fires etc for 3 to 5 seconds irrespective of the rev range. i.e it will behave the same at 6000 rpm and 2000 rpm until the throttle has been fully opened for the 3-5 second period.

The starving doesn't occur on slow roll ons.

I'm thinking it's a straight out 'speed of petrol delivery' issue.

After having been informed that filters I recently installed could cause problems unless it was for a low/no pressure delivery, I set out yesterday to find a bit of jointer pipe (tried Repco, Super Cheap, Bunnings, PlaceMakers - no joy) when visiting a mower shop to ascertain that they didn't have any suitable diameter pipe, I saw that they had some straight line small no pressure filters (better than the right angled monster I had installed earlier). So I paid $37 :roll: and tried the smaller filter yesterday afternoon and it has improved the running as is now running as described above.

I will be continuing with my search for a 50 cent length of 7mm outside diameter pipe so I can prove that I have now wasted a total of $50 on filters.

Any other thoughts? Carb diagphrams etc??

TIA

what's this for?
repco sells suitable fuel hoses by the meter

for proper troubleshooting i still think you first need to try it out without any filter

I want to remove the filter but my fat fingers can't get between the carbs to put a new hose onto the carb hose nipple (and don't fancy dissasembling the carb bank), so my fall back plan was to use a jointer to reconnect the hose from either side of the filter. I'm told that Mico's should have some. I was planing on calling in to Mico's tomorrow after work and trying it on the way home. I figured that a 7 or 8mm tube with 6mm internal diameter should be ok for the fuel flow and enable me to prove or rule out the filter

Bad plan?

Bad plan?

good plan, i think

i used the stiff thick-wall car fuel line so i was able to slide it onto the carbs nipple with a help of long-nose pliers only (the tank was off, of course)

I'm well and truly used to taking the tank off now... if it can be done without removing and disassembling the carb bank, maybe I should just grow a pair and do it.
