A retune is probably needed, I found mine was over-fueling once the surge tank setup was put on. Anyway, you made great power so enjoy it! 1 Link to comment Share on other sites More sharing options...

Saving for wedding next year...What's the cheapest (decent/reliable) surge tank I could get...Would a random $200 ebay surge tank (pump not included) do the trick? And if I'm running this Walbro, do I need to just get a 2nd similar pump or do I need remove that and get 2 more bigger pumps?Seriously got no idea how a surge tank works, where it goes and what pumps I will need....

And I bet the old walbro will be struggling at this power 1 Link to comment Share on other sites More sharing options...

You'll hear it all the time whining away though. 1 Link to comment Share on other sites More sharing options...

All got a bit confusing with what I actually need to buy.I don't care about noise hey...If a suitable option is 1 bosch 044 with a surge tank, then I'm happy with that option.
